TAS5805M: FS MODE

Kenta Yamada

Part Number: TAS5805M

Hi Teams,

The sampling rate of our application is 44.1kHz.

When FS MODE is set to 44.1kHz, Clock error occurs (Flag:CLK_FAULT_I).

And we confirmed register CLKDET_STATUS Register (Offset = 39h), but no flag is set.

When FS MODE is set to auto detection, no error occurs.

What could be the cause of these error?

Hi Kenta

Can you capture the waveform of your SCLK and LRCLK? What is their frequency separately?

Hi Shadow,

I got it.

I will capture the waveform.

Hi Shadow,

Green: LRCK

Magenta: SCLK

Hi Kenta

What I2C codes did you send? Also did you change anything else?

Hi Shadow,

Sorry for bother you.

Our configuration of "BCK_RATIO_CONFIGUR" is wrong.

Our system of BCK ratio is 64FS but setting of TAS5805M is 256FS.

After we set 64FS, the error has been resolved.

Thanks for your help!!
